A new OMI - FORTRAN

Our new Pond component will represent a two dimensional grid of values, specified by

an origin (x and y) - OriginX and OriginY will
be the argument names

a cell count (x and y) - CellCountX and
CellCountY will be the argument names

delta values (x and y) - DeltaX and DeltaY
will be the argument names

In our
example, OriginX and OriginY will be set to 0;
CellCountX will have a value of 6 and CellCountY
a value of 8; a value of 10.0 will be set for both DeltaX
and DeltaY.
These values will be used to initialise our component's grid and the component
will maintain the state of this grid between timesteps.

We will also add another argument to our OMI file - the value that each node on
our grid will have at the start of the run; the InitialNodeValue.
In our example this will be 1.
